Use Tilemap with several Bitmaps

Is it possible to use Tilemap to render several bitmaps? I understand that you’re supposed to use one Bitmap, however many third party frameworks such as Haxepunk allow you to use several Bitmaps. Any help would be appreciated.

In the Tilemap constructor, tileset is optional. If used, it applies this by default to all the tiles added to the Tilemap, but Tile has a tileset property as well. If you want, you can set the tileset per tile, or if you use a default tileset, just when you need a different one.

You can also use multiple Tilemap instances
